"They had to pull the ceiling in the kitchen and the bathroom," Schwemley said. "We were on that one for quite a while because the blown-in insulation tends to tunnel — it can burn for quite a while and you don’t notice it because there are no flames."

Schwemley said heat travels along the rafters of the home, making them turn black as they burn with no flames. Should that fire reach a portion of the home not covered with insulation, a larger fire would ignite.

"You have to pull the insulation out until you get to a spot where you don’t anything that’s burned," Schwemley said. "You could have rekindles when you miss a place where it’s still burning out."
